session-control in RequestProcessor

Hi all,

I am trying to implement a session handling around my application in
StrutsCX.

I read in "Programming Jakarta Struts" (o'reilly, Chuck Cavaness), that I
can extend the RequestProcessor-Class and need only to configure the
struts-config.xml to use this new class instead of the
Struts-RequestProcessor.

I would like to fetch any access by the RequestPreProcessor-Method, to
grant access when logged in, and redirect to the login-page when not logged
in!

My problem is, that tomcat crashes and my browser send me this error
message:

HTTP STATUS 503: Servlet action is currently unavailableH


Does StrutsCX does support "extending the RequestProcessor-Class"? If yes,
what I am doing wrong?

Greetings
Asarnusch

PS: Please be tolerant to my "school-english"
